4 Sheets-Sheet 2 W. KAssEBEER APPARATUS FOR CONVEYING AND LOADING CROPS`A 4 SheetsSheet 4 Filed June 17, 1922 erable form.= In this instance,l the upper end of the mast 14"has rigidly fixed thereto a casting 17 which is provided with two V arranged supporting journal boxesor arms, each of which carries a means for driving" the lowervend ofthe .shaft 46 is provided the hoisting chains g hereinafter described. As shown in Figures 3 and 4, each one of these journal boxes or arms 18.is suitably hollowed or cored out to form bearings for a shaft 19 onv which Vis carried a worm 20 meshing with a worm wheel 21carried on a shaft 22 located at rightanglesto the shaft 19. AOnthis shaftr22 is also mounted-a chain pulley 23 and a suitable guide pulley 24. Each one of'theseV-arranged blocksor bearings is provided with a relatively long extension comprising spacedtriangular r shaped arms 2,5, which are securedt'o the. blocksas at 26 and to a clamping block 27 secured to the mast 14. v-These; triangular beams 25 are braced by suitable cross bars 28. lThe outer ends `of Athe triangular beams provide spaced bearings for chainpulleys 2,9 and 30. These pulleys 'are constructed and. arranged v4.to

form a guideifor the ',outerr'end ofthehoisting chains.` These extensions 25 of the .V- arranged arms are braced at their-outer ends by means of a suitable crossbrace 31.' i1

In order to-move thisl turntable and the hoisting arms: carried y*thereby* rotatively `with *respect to theitractor and its `superstructure, certain driving mechanism ,is :arranged.- The preferred form of. this driving mechanism is shown, clearly in Fig. 6 wherein the base-of the mast 14` is provided twith a concentrically attached wormfwheel 32 which in turn meshes with.v a worm33 mounted on a shaftf34 carriedy in suitable bearings on the super-structure. The shaft 34 also carries a large gear 35 and a smaller gear 36, the former meshingV with a gear 37 and the latter meshing with a gear 38both of which are fixed on a counter shaft B9 alsoV -carried in bearings 'on the' tractor frame.

yThe gears 37 and 38 are looseon shaft 39 but are connected thereto by means of a clutch 40 splined on shaft 89 andf adapted to be thrownin either direction -to couple gears 37 and 38 to the shaft 89. 'Asuitable lever 41 operable from, a" convenient. point on thetractor is provided for* shifting this clutch'40. The lower. end; of theniastis provided with anV upper l plate.which is, supported .y onya plate 42 mountedfony the-*trac- .,tor, suitable ball fbearings 43 providing the necessary bearing.- y..

.- In. order :to `raise vand 'flower the'` hoisting chains 44 carried by the `hoisting-arms 25,

there Vis providedz vsuitable `d rivi'nglmechamsm comprising a vertical, shaft- 46 which projects vertically upwardly 'throughy the lmast y14 concentrically therewith. Itis pro-v vided, on its upper end with ,a bevel gear 47 kwhich meshes withfbevel, gears 48 andv 149, Veach mountedon the innerl end ofY its respecldrive in orV out in the usualmanner.

.carried by these hoisting arms.y

tiveshaft 19, carried on each bearing block 18.- In this manner, the. bevel gears 48 and 49 always mesh with the bevel gear 47 irrespective of the position ofthe hoisting arm 18V relativeto the tractor( In a like manner,

with a bevel gear 50 which meshes with ybevel. gears 51 and-'.52 mounted on shaft 39.

Vmeans of 'thisc'onstructiom the chains 44 can be either raisedor lowered. The shaft 39 is drivenby meansv ofra belt 55 connected tothe 'y -wheelfif'of the 'engine and' to asuitable pulley 56 controlled bymeans of'a shi-ftable pulley 57 mounted on van arm.y 58 controlled by a lever 59 to tighten or loosen thebelt when it is 4desiredtoth'rowthe blt Y means of the above. arrangedl construction, thepower'fplant of thetractonis utilized to not only move the .hoisting arms angularly in a horizontal plane to position them .at any point about the-tractor, ybut also is utilized to raise'orlowerrthe hoisting chains Then a load of-sugar cane has been placed in the baskets lor boxes in the field, and the .hooks'44 on the' chains 44lhave engaged the usual 'ey-esjof theseboxes for raising the same, by meansk of the vhoisting mechanism,

the boxes fullof'sugar cane can then be lifted off theground. In this position, jit` is ydesired to 4supportfthese boxes-full of. sugar cane on the tractor itself while the tractor is traversing from the loadingposition to the train of cars. To this end,Y suitable mechanism is arranged on the tractorV [swinging Vthe laden boxes Vinwardly to the tractor frameand for Athere supporting the boxeson :the frame. YFor this purpose, the tractor lframe is provided with a yprojecting vledge 59 which preferably extendsr4 around the `sides `of .the tractor so lthatvwhen the inner edge of the box iis-supported thereby, it will constitute the necessary vsupper,ting platform. if The means for swinging theboxes inwardly on to these ledges,"comprise asuit- ,able number of chains 60 which are adapted ton-be wound around ',shaftsfl and:` 62"`car ried bythe tractor frame. These shafts 61 and r62. are driven bymeans of ,worm wheels Y63 which in yturn mesh with a worm 64 mountedfon ashaft65 operated by means of Valhand wheel66. Thus when thebasket is in the position shownfto the right of Figfl, itcanbe raised slightly, atwhich time, the hookon@v the chain 6() is inserted through' a suitableeye on the basket. The hand wheel 66 jis then operated to `wind the chain. about its shaft and thereby draw -theabaskets'xor boxes inwardly `ontothe supporting ledge 59 to carry the baskets from one place to another and to take the strain off the hoisting mechanism during this interval. It is obvious that any other suitable form of mechanism for accomplishing this function may be substituted, and practically the same may be driven from the power plant of the tractor if desired.

The boxes for the sugar cane are constructed of any desired material and of any size. These boxes are preferably provided with two doors hinged to Open in the center. The doors are held in position by means of the usual link mechanism and are operated to be released by means of the suitable pull lever. Instead of these boxes, slings can be used.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing` from the spirit of the invention as set forth in the appended claims.

Having thus described the invention, what I claim as new and desire to secure by LettersPatent, is

In combination, a frame, tractor treads carried thereby, means for actuating said treads to project the frame, a hoisting device mounted on said frame, means for swinging said hoisting device to position the same over either side of said frame, means to operate said hoist to raise a load, load supporting ledges located along either side of and near the base of said frame, and
